HI @as.aljohani ，
The wiring sequence of this hardware interface is different. Cannot directly connect to VIM4. If you need to use LCD, we recommend that you prioritize the ones we support officially.

Thank you for your response. I need this screen with this (size) and these specifications. If you provide such a size, provide me with the link. If it is not available, can you guide me through the steps of how to add it?

Note: We made a special board to be between the screen and VIM4 to make it work, and we took into account the electrical connections to make it compatible with VIM4 based on the datasheet.

Any response? I’m sorry but we don’t have much time.

Hi @as.aljohani , we do have a 10.1inch display which is not listed on our Khadas shop yet. Would you pls provide your email so I could send over the details for it?
